IPC: C23C2/02
Filed: 1994-03-25
Abstract: A galvanized steel sheet has a coating layer of protective material applied to its surface where the steel sheet has been roughened prior to application of the protective material. The improvement is characterized by the roughened steel surface having a pattern which ensures desired consistent quantity of coating during application of the protective material. The pattern provided on the sheet surface has a multitude of depressions defined by a plurality of ridges. The upper surfaces of the ridges defining a plane for each side of the steel sheet, where the ridges have a surface area less than the nominal surface area of the sheet side. Each depression has a depth defined by a continuous side wall extending into the plane of the sheet side.     The side wall slopes downwardly of the plane at an angle greater than 45°.  The multitude of depressions on the sheet side picks up a sufficient quantity of coating material to provide the desired consistent quantity of coating on the sheet surface when solidified and adhered thereto.

Title: Gravity controlled potentiometer
Inventor: REBIC JEAN-CLAUDE
IPC: G01C9/10
Filed: 1994-05-12
Abstract: A level is a tool used to determine whether a surface is horizontal or inclined with respect to the gravitational field. A level requires a sensing mechanism to measure an angle with respect to the gravitational field, the most common being an air bubble in a liquid filled tube. In this invention, a potentiometer type sensor is used to measure the exact surface angle with respect to the gravitational field. Since this Gravity Controlled Potentiometer uses an electrical current that varies with respect to its position to the gravitational field, this sensor could be interfaced with an electronic circuit.

Patent CA-2146854-A1 (CA)
Title: Recombinant specific binding protein
Inventor: HARRIS WILLIAM JOSEPH
IPC: C07K19/00
Filed: 1993-10-15
Abstract: A specific binding protein having first and second binding regions, e.g. antibody Fv frag-ments, which specifically recognise and bind to target entities, said binding regions being con-tained at least in part on respectively first and second polypeptide chains, said chains addition-ally incorporating respectively first and second associating domains, e.g. antibody VH and VL domains, which are capable of binding to each other, causing the first and second polypep-tide chains to combine, thereby providing a single protein incorporating the binding specif-icities of said first and second binding regions. The first and second binding regions may re-cognise different target entities, giving a bispecific binding protein. Preferably the associat-ing domains are derived from a human protein (i.e. one which has been exposed to the human immune system), so that the protein is less likely to provoke the human immune sys-tem when administered therapeutically. The binding protein is suitably produced by recom-binant DNA expression.

Title: Stable lipid emulsion
Inventor: SUZUKI HIDEKAZU
IPC: A61K9/107
Filed: 1995-07-10
Abstract: A lipid emulsion which comprises (A) an oil component, (B) an emulsifying agent containing yolk lecithin and/or soybean lecithin, and (C) water, wherein the lipid emulsion further comprises citric acid or a pharmaceutically acceptable salt thereof and at least one member selected from the group consisting of methionine, phenylalanine, serine, histidine and pharmaceutically acceptable salts thereof, provided that it does not simultaneously contain methionine and phenylalanine.
